GEORGE OULTON, OF LIVERPOOL, ENGLAND.

JET-DIFFUSER.

SPECIFICATION forming part of Letters Patent No. 540,818, dated June 11,1895. Application filed Maroh'B, 1894. Serial No. 502.381. (No model.)Patented in England October 10, 1893, No. 21,386-

To all whom it may concern.-

Beit known that I, GEORGE OULTON, a subject of the Queen of GreatBritain, residing at Liverpool, in the county of Lancaster and Kingdomof England, have invented certain new and useful Improvements in Jet-Diffusers, (patented in Great Britain October 10, 1893, No. 21,386,) ofwhich the following is a specification.

This invention relates to nozzles and devices inconnection therewith forspreading out or diffusing jets or streams of fluids or converting theminto spray as they issue from the nozzle, and the object of myimprovements is the production of a simpler and more effective devicethan has hitherto been made, by means of which the diffusion of the 'jetand the density of the spray can be instanta neously regulated at willwhile the jet is issuing from the orifice in an analogous manner as canbe done by covering or partly covering the orifice with the thumb of thehand, and which at the same time acts asa valve for stopping the jet orclosing the orifice completely and thus renders the use of another stopvalve. or cook in connection with the nozzle superfluous.

On the accompanying drawings a nozzle fitted with my improved device isrepresented, Figure 1 showing a side View thereof, partly in section;Fig. 2, a similar view of the end part with the orifice partly closed;Fig. 3, a front View; Fig. 4, a plan of the sliding loop, hereinafterreferred to.

The improved jet dilfuser consists of a tubular barrel or nozzle ahaving an end-plate with a contracted orificeb and a flange b and formedwith a lug a, to which is hinged a leverchaving a finger-plate c at thelower end and a socket c at the upper end. Into the socket is fitted ablock at which forms the stopper or spreader made of some elasticmaterial such as india-rubber preferably and secured by a screw plug 0or by any other suitable means. The block (:1 may be solid or hollow. I

The lever c surrounds the tubular barrel a to enable the device to beoperated by a pull- An alternative arrangement is indicated by thedotted lines showing a thumb-plate extension 0 of the lever c on thefulcrum side of the barrel a. In this lattercase the lever is pressedaway from the barrel. The lever c is so formed that when free, a

jet issuing from the orificeb shall pass the block 0 without strikingit, as shown by Fig. 1. Upon moving the finger-plate c of the levertoward the barrel to or pressing the thumbplate- 0 away from the barrel,the block is moved toward the orifice b and brought first into contactwith the edge of the orifice next to the fulcrum of the lever andgradually covers the orifice, so that a jet issuing from b strikes theblock 0 and is more or less diverted and diffused accordingly as theorifice is more or less closed or covered by the block, as shown by Fig.2. The block or spreader 0 being of an elastic nature and presentingalso an inclined face to the orifice the amount of contact between itand the edges of the orifice, and the partial closure of the latter canbe varied by moving the lever c nearer to or farther from the barrel aand the jet diffused and the spray projected as may be desired. Theflange 1) serves to protect the hand against liquids dripping upon it.

In order to close the orifice entirely and stop the issuing of the jet ashackle eis placed round the barrel a which can be slipped over thefinger plate 0 of the lever and thus relieve the hand from having topress the lever. Obviously other ordinary means for stopping the flow ofliquid to the nozzle may be used instead of or in addition to the same.

A couplingf may be formed at the end of the barrel a for readilyconnecting a hose or other pipe to the barrel. Any suitable coupling ormeans for coupling the parts together may be used, the arrangement shownon the drawings being the well known cone coupling.

I claim as my invention 1. The combination of a tubular barrel having anorifice at its end, a flange atthe orifice formed with a lug, a leverpivoted to the lug, a ring formed upon one arm of the lever andsurrounding the barrel, the lever being extended to form the handle, asocket formed on the other end of the lever, and a hollow block ofelastic material secured in the socket by a screw plug and extending tothe edge of the orifice.

2. The combination of a tubular barrel having an orifice at its end, aflange at the socket formed on the other end of the lever orifice,formed with a lug, a lever pivoted to and a block of elastic materialsecured in the the lug and extended to form the handle, a socket by ascrew plug and extending to the ring for surrounding one end of thehandle edge of the orifice.
